Research Focus: theoretical computer science, design and analysis of algorithms, with an emphasis on approximation algorithms for NP-hard problems, metric embeddings and algorithmic techniques for massive data set

Research Focus: intersection of nanoelectronics and nanoscale energy conversion. Most projects include both fundamental and applied, experimental and computational components. Some recent topics (as of 2013) include: Energy-efficient transistors, memory

Research Focus: vision science, spanning topics from visual disorders, reading development in children, to digital imaging devices and algorithms for both magnetic resonance imaging and digital imaging

Research Focus: designing algorithms for shortest paths, pattern detection and other computational problems in graphs and matrices, and computational issues in social choice: when and how can one efficiently manipulate elections, tournaments and competitions, how to meas
